-LRB- CNN -RRB- -- The anti-shark 's fin campaign is crusading on in Asia Pacific .

Air New Zealand has become the latest airline to stop flying shipments of shark 's fin to Hong Kong , the shark 's fin capital of the world .

The decision came about after the New Zealand Shark Alliance revealed the airline 's shipments in local media .

`` Air New Zealand has taken the decision to suspend the carriage of shark fins while we undertake a review of the issue , '' Air New Zealand spokesperson Andrew Aitken told CNN . `` We have no further comment to make while this review is underway . ''

The topic is a particularly sensitive environmental issue in Hong Kong , the world 's biggest market for shark 's fin , as campaigns highlighting the cruelty and devastation stemming from the practice are becoming more and more successful .

Prominent hotels and restaurants in the city have been publicly striking shark 's fin from their menus , while Hong Kong 's main carrier Cathay Pacific also announced a ban on shark 's fin cargo last September .

`` Due to the vulnerable nature of sharks , their rapidly declining population , and the impacts of overfishing for their parts and products , our carriage of these is inconsistent with our commitment to sustainable development , '' said Cathay Pacific 's statement at the time .

Approximately 72 million sharks are killed each year and 10,000 tons of fins are traded through Hong Kong .

Conservation groups say there is still far to go in terms of education and awareness .

`` We were delighted to hear that Air New Zealand is following suit of the Cathay Pacific announcement , '' Hong Kong Shark Foundation director Claire Garner told CNN .

`` Airlines need to know what they 're carrying and how they are impacting environmental sustainability . ''

`` It can be quite tricky in terms of monitoring and managing shipping as shark 's fin is transported in a dried form and the packaging can be made to look like other kinds of dried seafood , '' said Doug Woodring of the Ocean Recovery Alliance in Hong Kong .

`` Decisions -LSB- like Air New Zealand 's -RSB- can have a big impact on reducing consumption in Hong Kong . ''

Fiji-based Air Pacific was another airline that came under fire from environmental groups for carrying shark 's fin cargo earlier this month .

A report in Hong Kong 's South China Morning Post said the airline had run a contest for Hong Kong weddings that did n't feature shark 's fin in the menu -LRB- a popular wedding banquet menu item -RRB- and offered honeymoon flights to Fiji as the prize .

Air Pacific and New Zealand Shark Alliance were not available for immediate comment .
